Android?

[TailsFanLOL]

Could this ever be adopted to play Android Unity games on desktop, or the other way around, desktop Unity games on Android?

I don't know how Unity works precisely but I would imagine that mobile games would be usually looking for something GMS related which would crash them on desktop. As for the reverse, even if it works it might not work on a typical phone because there's probably much more native (architecture specific) code than the Unity Player involved in such a complex game engine...

But might be worth a shot.

I tried this once and couldn't get it to work. May be worth to test with a minimal example to see if its generally possible. I think android uses OpenGL ES and I'm unsure if the linux player supports it. Also, most android games are only for arm64, so when targeting linux amd64, all the native code needs replacement.

Other use cases I could imagine that are more likely to work:
Windows, Linux -> Mac
Mac, Linux -> Windows (although the most uninteresting one)
